Chris, to add to what Notes said: the notation in BIAB for a RealTrack is there for educational purposes. It is not actually played by the program, so modifying it has no effect. It is possible to export the MIDI to a DAW where you can edit it and supply your own sounds, but the MIDI from these RealTracks lacks the nuances of an actual performance.
